Paradigm Shift in Mid-IR Fibre Laser

该项目引入了3.5微米中红外光纤激光器的范例转变。为了获得高功率、简单、坚固耐用的中红外光纤激光器设计，将研究一种新的激光工艺。我们将使用先进的光谱学来描述光纤激光器的动力学，使用计算机建模来优化激光器的设计，并通过实验来演示这一概念。新设计将实现灵活、高精度的聚合物加工，以适应不同聚合物中碳氢键的独特吸收线，目前缺乏高功率、高亮度、低成本的光源。它还将为非常高分辨率的激光辅助玻璃3D打印打开大门。该项目将使澳大利亚在先进制造业方面拥有新的优势。

This project introduces a paradigm shift in 3.5µm mid-IR fibre lasers. A new laser process will be investigated to obtain high-power, simple and robust mid-IR fibre laser design. We will use advanced spectroscopy to characterize the fibre laser dynamics, computer modelling to optimize the laser design, and demonstrate the concept experimentally. The new design will enable agile, high precision polymer processing tailored to the unique absorption lines of carbon-hydrogen bonds in different polymers where there is currently a lack of high power, high brightness low-cost light sources. It will also open the door for very high-resolution laser assisted glass 3D-printing. The project will give Australia a new edge in advanced manufacturing.
